CONFIDENCE INTERVALS FOR THE DIFFERENCE IN 2 POPULATION PROPORTIONS Pharmaceutical scientists tested the effectiveness of a new drug designed to cure malaria. They recorded the proportion of rats that were cured when given the existing drug (sample 1 proportion) and the proportion of rats that were cured when given the new drug (sample 2 proportion). The 95% confidence interval for the difference in the proportion of cured rats between these two groups was (-0.18, -.005). Interpret this interval. O p1 is substantially more than p2, therefore we can be 95% confident that the proportion of rats cured is substantially higher when given the existing drug verses the new drug. O p1 is substantially less than p2, therefore we can be 95% confident that the proportion of rats cured is substantially higher when given the new drug verses the existing drug. O p1 is similar to p2, therefore we can be 95% confident that the proportion of rats cured is similar, whether given the new drug or the existing drug.
